There is one pre-built binary included with this code distribution in the production/win32_helper folder. Feel free to not trust it. short_path.exe: This tool is built by the feisty meow application bootstrapping process (that is, by scripts/generator/bootstrap_build.sh), but unfortunately it is needed *by* that process when your visual studio installation path has spaces in it. To fix this chicken & egg problem, you can manually change your VC root variable (e.g. VS100COMNTOOLS) to the short path version (as reported using "dir /x").
